Reaction Steps
To a solution of 7-(2-morpholin-4-ylethyl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (149 mg, 0.6 mmol) in DMF (3 ml) at −20 C was added 1,3-dibromo-5,5-dimethylimidazolidine-2,4-dione (69 mg, 0.24 mmol) in three portions. The reaction was stirred at −20 C for 3 h. Upon the completion, the reaction was quenched with aqueous saturated Na2SO3 and allowed to warm up to rt. The crude was extracted with ethyl acetate. The organic layer was collected and washed with brine, dried over Na2SO4 and concentrated. The resulting crude was purified via column chromatography (95:5 v/v CH2Cl2—CH3OH) to afford 75 mg of the title compound as yellow solid (yield 39%). MS [M+H]+=326.2; LCMS RT=1.15 min.
